About the Airtac SC80 Standard Cylinder SC80X670STC
The AirTAC SC80X670STC is a double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. With an 80 mm bore and a 670 mm stroke, its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for mid-to-heavy linear motion tasks.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC suffix) that includes the TCM1 bracket for pivoting applications. The total extended body length is approximately 852 mm, making it a compact alternative to longer ISO 15552 profile cylinders.

Where the Airtac SC80 Standard Cylinder SC80X670STC Is Used
Conveyor Diverters
The 670 mm stroke and centre trunnion mount allow the cylinder to pivot, making it ideal for actuating diverters or gates on wide conveyor lines.
Material Clamping
With 2513 N of push force, this cylinder provides robust clamping for woodworking or metal fabrication jigs where the trunnion mount simplifies alignment.
Pivoting Press Mechanisms
The TC mount and built-in magnet for end-of-stroke sensing make it suitable for small pneumatic presses that require a swinging motion to load and unload parts.
Is the Airtac SC80 Standard Cylinder SC80X670STC the Right Cylinder?
Select the SC80 when your application needs between 2513 N and 4523 N of force. If you need a higher force class, step up to the SC100 bore which provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore offers 1559 N at the same pressure. The 670 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
For a stroke of this length, ensure the 25 mm rod is protected from side loads. An external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear. When replacing an existing cylinder, match five points: 80 mm bore, 670 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet for sensor compatibility.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X670STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The SC80 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the valve is centered. The adjustable air cushion only decelerates the piston at the stroke end. For load holding, you must add a pilot-operated check valve or an external rod brake.
